Hi Hussein, great article, thank you for laying it all out for us. I specifically like the overview from your schema-registry on docs.confluent.io.

One addition, do you know Delta Lake (https://delta.io), they might also have some features you are looking for. Especially the transaction log, where all changes are protocol-ed, including the schema (Schema Evolution & Schema Enforcement). Plus they have many more databases like features for data lakes on top like time-travel, ACID Transactions, updates and deletes and it’s all based on top of Parquet files.
